Pretty little liars. is A one of the liars?

there has been some talk about Aria being A for awile. It would be so horible if one of the liars was A but, ya know. Now, I just saw a picture on facebook about how Aria twirls her straw in the glass the same way A did... but there is alot of info on why aria could be A. - But, what would her motive be? As far as we know she has nothing agenist her best friends. And what would she go to Mona for, since she was the old A. Emily. I was thinking about how maybe she was mad at maya for leaving her and she got so upset that she bought the pills from lucas and constantly got wasited over maya. Or she was sick of being poor emily. - Now, I really doubt that emily is A becasue she is too sweat and why would she threaten and poison herself? hanna. She had a relationship with Mona so she could have planned everything with her... - ...but, she wouldn't agree to get hit by a car. Spencer. She has been help Jason alot who was apart of the nat club so if the club has anything to do with A then maybe she could want to join. Also, spencer is very smart and could easily be A - but she probably isn't. I don't think that any of the pretty little liars is A because they wouldn't gop agenst eachother like that.
